Abstract

Advantages and disadvantages of forward and push-pull converters for a power region of several kW are overviewed in the beginning of the contribution. Further an optimization of the power pulse transformer of the standard two-switch forward converter is proposed. The goal of the optimization is to ensure minimum total transformer volume at constant predefined parameters: maximum core flux density, DC-link voltage of the converter, output voltage of the converter, output power, current densities in the primary and secondary winding and switching frequency. Optimum size and geometrical proportions of the toroidal ferrite core are the results of the optimization. An analytical approach is used in the optimization (searching for a local minimum of a function). Practical results for a converter with output parameters 1 kW/60 V are included to document the optimization task.
